Application filed Apri13, 1912. Serial No. 688,236.

To all whom, t may conc-ern:

Be it known that l, MICHAEL KELLY, al

citizen of the United States, and a resident. y

of the city of'New York, borough of Manhattan, in .the county and State of New York, have invented a new and lmproved Water-Jacketed Stove, of which the following is a full, clear, and exact description.` V

My invention relates to a combined oil vo r gas stove and a water-jacketed oven.

An object of my invention is to construct a combined stove, one part of which is an ordinary gas or oil stove designed to heat a water-jacketed oven to a definite temperature, thermostatic means being provided for removing the heater to an inoperative position relative to the water in said jacket, so as to maintain said oven at a constant temperature.

A further object of my invention is to provide means for uniformly distributing the water through said water jacket.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of re'ference indicate'corresponding parts in all the figures, and in which- Y Figure 1 is a vertical longitudinal sectional view of a preferred embodiment of my invention taken on' the line 1-1 of Fig. 2 and looking in the direction of the arrow; Fig. 2

is a plan view of the stove shown in Fig. 1;

Fig. 3 is a transverse sectional view taken on the line 3 3 of Fig. 2; and Fig. 4 is anenlarged horizontal transverse section, showingr a bifurcated joint between the heating coil and distributing pipe in, the water jacket. i

Described more in detail, I have' shown a stove comprising an outer, preferably vintegral, shell 5, closed in front by means of a door 6, and having a back 7 integral with the shell. The relatively flat top 8. has formed therein a series of concave c upshaped heating depressions 9. Disposed wit-hin the shell 5, fastened tothe front 10 thereof and spaced from the inner walls of the shell, and from the back 7, is a shell 11'v forming the oven, one end of which is closed, by means of the door 6, the opposite end of which is closed by means of the back 12 integral with the shell. The shell and back forming this oven are corrugated in order to increase the radiating surface of the oven.` The space between the oven and the shell 5 is practically filled with water or other suitable fluid, which is introduced into the same by means of an inlet 13 at the top rear portion thereof and may be withdrawn by means of a cock 14 shown in the lower central portion of the shell 5. Steam pressure within the stove is indicated by means of a gage 15. i

Mounted upon the rear of the shell 5 and extending from the top thereof, is a suitable supporting plate 16, and extending from the bottom and rear of the shell 5 is a bracket 17, the outer end of which bracket forms a bearing for the lower end of a shaft 18, the upper end of which shaft is positioned adjacent the outer end of a strap 19 affixed tothe central rear portion of the .plate 16. Connected to said shaft 18 and rotatable therewith upon the bracket 17 is a tube 20 extending on opposite sides of the' shaft 18. @ne end of this connect-ion with an oil o-r gas reservoir 21,

-and the opposite end leads to a suitable burner 22. The upper end of the shaft 18 is provided with a stud 23, whereby the shaft is centered and supported at its upper end by said strap 19. Rigidly attached to the upper endI of the shaft 18 is an outwardly extending arm 24, attached to the free end of which arm is one end of a thermostat 25, which thermostat extends above the burner 22 and has its opposite'end suitably attached to a bracket 26 carried by the back 7 below the plate 16.

It will be seen by the above-outlined construction that heating the thermostat will cause the burner to swing from its position beneath one of the spiders 27 to another spider. DisposedV above the burner 22, when in normal position beneath one of the spiders 27, is a coil of tubing 28, each end of which leads to an inlet 29 of one of a pair of Ys 30,l one disposed the other disposed adjacent the bottom of the rear of the shell 5 just within the back 7. As ,shown more particularly in Fig. 4, each of'these Ys. 30 has a central partition 31 adapted to divide the current of water passing through the vtube 28 into two stgreams, as shown by the arrows in said figure. each of the Y.s, is a pipe 32 extending forwardly throughy the water space between the oven 11 and the shell 5, so as to oonductNthe Watex` to and from the -front of the oven,

tube is in fluid adjacent the top and Threaded into one of the branches of jacket, a heating coil exterior to said jacket and communicating therewith, a--bifurcated extension connected to each end of said coil on the inside of the jacket, the bifurcations on the extensions being of unequal lengths, a pair of supports extending substantially parallel to each other at the end of .the stove, a heating device between said suplports and adapted to rotate on a vertical axis extending between said supports, said heating device in one position being adapted to act upon said coil, and thermostatic means associated with said coil to swing the heating device around its axis away from said coil when the temperature of the coil reaches a predetermined degree.

2. A stove comprising a closed outer shell, an oven Within said shell and spaced from the same in order to form a water* jacket about said oven, and a heating coil disposed exteriorly of said stove, the opposite ends leading into the water' jacket at the top and the bottom of said stove, each ot said ends being bifurcated', said bifurcations being of unequal lengths, to introduce and withdraw the water in said jacket to and from different portions thereof.

3. In a stove, the combination of a shell, a supporting plate extending from said shell, pivoted heating means disposed be'- neath said plate, a heating coil disposed between said plate and said heating means, said coil leading into said shell to heat the same, a thermostat disposed between. said coil and said plate, and means controlled by said thermostat for swinging said heating means on' its pivot, to remove the same from said heating coil.

In testimony whereof I have `.signed my name to this specification in the' presenceof two subscribing witnesses.
